Since his first recording for ECM more than 30 years ago, Keith Jarrett’s discography has expanded into one of the unique achievements of the age, setting standards in a multiplicity of directions. His :rarum double album gives an indication of its breadth and depth. Alongside music by the Jarrett/Peacock/DeJohnette trio and the “Belonging” quartet with Jan Garbarek, Palle Danielsson and Jon Christensen, Jarrett provides an overview of his work as solo improviser. The culmination of his 1981 Munich solo piano concert is included – released on CD for the first time – as well as selections from his 1987 Tokyo solo concert and an encore from Bregenz. Jarrett also re-examines his innovative clavichord improvisations from the 1986 “Book of Ways”, and pieces from the uniquely-inspired “Spirits” (1985) tapes. One of Keith Jarrett’s goals for this compilation was, as he writes in his liner notes, “to direct the listener’s attention to recordings that either have been heard less than I feel is their due, or have escaped recent awareness.”
